The basic idea...

"The basic idea behind open source is very simple. When programmers on
the Internet can read, redistribute, and modify the source for a piece
of software, it evolves. People improve it, people adapt it, people
fix bugs. And this can happen at a speed that, if one is used to the
slow pace of conventional software development, seems astonishing...
...The Open Source pages exist to make this case to the commercial world." - Introduction to Open Source - www.opensource.org

* BitcoinSpinner

BitcoinSpinner is a light-weight, secure, and user friendly Bitcoin wallet for Android.

Feature Overview:* Send and receive Bitcoins using QR codes.* One-time wallet backup using a QR-code that can be restored on another Android device.* All your Bitcoins are protected using private keys stored on your device using app private storage.* No heavy block chain download, BitcoinSpinner is ready for use immediately.* Address book* Transaction history.

BitcoinSpinner is NOT an on-line Bitcoin Bank. Nobody can run away with your Bitcoins. It is implemented on top of the BCCAPI, which means that all the heavy lifting associated with managing the block chain is done by a server. The server side is in no position to spend your Bitcoins, as all private keys are stored on your device. More info on the BCCAPI here: http://goo.gl/OqvQ9
